Tests that FindText() returns 5 for parameters "more" and "We'll continue our quest in space. There will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space. Nothing ends here; our hopes and our journeys continue!" Test feedback FindText() incorrectly returns 0."
I wrote this program, but the solution on zybooks didn't let it full credit.
It showed:

getline (cin, text);

do {
option = PrintMenu(text);
